New Release of the Self-Monitoring Blood Glucose Meter ’GLUCOCARD G Black’
-Helping diabetes care with treatment support functionality-

ARKRAY, Inc. (Headquarters: Nakagyo Ward, Kyoto) will release a new self-monitoring blood glucose meter, the GLUCOCARD G Black on Wednesday, 8 May. It comes equipped with specifications that patients now demand: ease-of-use with color LCD, as well as functionality allowing data analysis to support of diabetes treatment and for the review of past measurement results. In addition, the system is the first in Japan to come with wireless connectivity to a diabetes data management system1) and is highly effective for daily blood glucose management.

The current number of diabetes and pre-diabetes patients in Japan stands at approximately 22.1 million2) and is increasing every year. This equates to about 1 in 4 of the adult population. Diabetes also presents a risk of complications such as diabetic retinopathy, diabetic nephropathy as well as arteroschlerotic diseases. To prevent this from occuring, it is important that patients identify their own symptoms and manage their blood glucose from an early stage. In light of this, we have been seeing increasingly diverse news about self-monitoring blood glucose meters used to measure blood sugar. The simple and accurate measurement of blood glucose is closely related to the evolution of result management, the treatment of diabetes and the extensive use of education and training.

The GLUCOCARD G Black, due to go on sale from ARKRAY, incorporates a color LCD, screen displays covering measurement operation and how to deal with errors and other elements for ease-of-use. The system also contains measurement result analysis and review functions to support diabetes treatment. The GLUCOCARD G Black is the first self-monitoring blood glucose meter in Japan to come with wireless connectivity allowing the transmission of measurement data to a diabetes management system which in turn allows patients to easily manage their own blood glucose values.

In 1970, ARKRAY was the first company in the world to succeed in developing a simple measurement device for blood glucose. Over the following 40-odd years, ARKRAY has remained committed to improving patient QOL and supporting treatment and education at medical facilities through both self-monitoring blood glucose meters in the GLUCOCARD series, and diabetes management systems.
